Excuse me, what is the treatment of hydraulic engineers in shield? If an electrical engineer, what are the requirements for PLC?

let me make some suggestions based on my personal experience.

The hydraulic systems of European and American shield machines such as Herrick, Wilt and Robbins are complex. If you have a high hydraulic level, are familiar with their principle drawings, especially the control system, and can also test the control pressures of each road, and are better at judging and handling faults, you can take a higher position and get a high salary. If you have a monthly salary of 1, in the construction unit, you will still have it. If you have it in the manufacturer, you will have higher technical requirements and better treatment.

Electrical engineers are also divided into several levels. Generally, the engineers on duty only need to understand the drawings of shield machines, and they can handle most faults of shield machines, so the treatment is low. Intermediate engineers need to know plc, such as Siemens 4 plc used by Herrick, and those with stations, can understand logic diagrams, and can judge faults according to monitoring diagrams. The treatment is good, with a monthly salary of 1,. Senior engineers need to modify plc programs.
